Abstract
The damping of collective states is a subject of broad interest, espec ially in finite many-body systems. We present a model to explain the s aturation of the spreading widths of giant resonances in hot nuclei an d the spreading widths of multiphonon states in terms of the chaotic d ynamics governing the coupling of collective motion to incoherent degr ees of freedom.
